Guys, I appreciate your help.
When I said Black Market I meant those ElectroMechanical repair people who have everything you can imagine of hacked tools, machines and softwares for any car brand...
One machine is meant to intercept the signal between the Key and the car, get a full analysis on how they interchange coding and stuff, take into consideration the VIN maybe and program a new electronic chip to be used with the new key they're making!!!!
Beleive me, the new key will be better than the original one when it comes to performance and even looks

...We're talking pro. here!
Now the risk that one can take here is considering that those hacked materials work like the original BMW ones and BMW doesn't have an "inner" system to detect if the key used is a hacked one and everyone will be happy

. Otherwise, busted EWS like the dealer told me!!
What do you think?!
p.s.: As for the price, that's what the dealer said, 400$! Tehy're gonna ask for a replacement from Germany or the US I donno and I live in the Middle East!
